It's understandable that the majority of the respondents here would pick UChicago over Cambridge as the majority of the respondents here are British. But I think the "elite" students in some top US schools would choose to go to Cambridge over UChicago in a heartbeat. Being able to study in Oxbridge for the Americans is a boast to his/her credentials. The Gates schoalrship, for example, receives many applications from some of the finest grads from top US schools like Harvard, Yale, Stanford, Berkeley, to name a few, wanting to pursue grad schooling at Cambridge. The Gates scholarship is extremely competitive. UChocago is an excellent school but Cambridge is simply better -- in almost all angles you wanna see it.
